MACHINE DRAWING 211 put in, it is safe to say that several hours5 extra time would berequired for this one item alone. But the drawing would be nobetter for shop use. Hence all bolt heads and nuts have been leftout, except when necessary to show clearance. An assembly or general drawing of this character should belaid out strictly from the dimensions shown by the details. Itthus serves a valuable purpose in checking up figures, and showingwhether or not the parts will go together. The method or char-acter of the work in no respect differs from that suggested for thedetail drawings. If a scale of 3 inches = 1 foot be used, the size of sheet mustbe 24 inches X 36 inches. The student, however, will perhaps findit easier to use a scale of 1J inches = 1 foot, in which case the ordi-nary size, 18 inches X 24 inches, will suffice. For such a small scaleit will be found undesirable to attempt to put in any very smallfillets and corners, although those that can be readily handled bythe ordinar
